Question

Quizplus · Accepted Answer

Both technicians are correct. Leading-trailing shoe drum brakes can have either cam-type adjusters or starwheel adjusters. Cam-type adjusters use a threaded shaft and cam to move the brake shoes in and out, while starwheel adjusters use a rotating wheel to adjust the distance between the shoes and the drum.
